idualwifi 7260 no connectivity after update

Disable the device and enable causes a KDL

KERN: iwm: fw chunk addr 0x800000 len 98304 failed to load
KERN: iwm: could not load firmware chunk 0 of 4
KERN: iwm: failed to load init firmware

Combined with the KDL, I am guessing that the firmware task got stuck, somehow.

I think I am going to need you to drop into KDL manually, before the first failure, and poke around to see what is happening at the time this problem occurred. Can you do that on this machine?

Can confirm this exact issue on a Lenovo Thinkpad X250.

This problem does not happen on my device which has a 7265D, but it does happen on a different device which as a 9260. After some debugging, I determined the problem is that no interrupts are being delivered at all, a fact which the kernel debugger confirms. Disabling MSI-X in the driver, or even MSI, does not help; still no interrupts are delivered.

This 9260 used to work with the old FreeBSD driver (albeit not especially reliably; I would occasionally get "failed to wake up the nic" and it would not start without a warm reboot), so clearly something changed. I'm not sure what, though. Perhaps korli might have some ideas? (Does he possess any devices supported by this driver?)

I will investigate more later. However I will not have access to the machine with the 9260 for a few days, so it may be a bit before I can try anything else.

Fixed in hrev56202.

I’m on hrev56350 with a Thinkpad E11(idualwifi 7260), and I’m still having this exact issue. I’ll try to investigate.

That will be some other issue. Please make sure your wpa_supplicant package is fully up to date as recent changes there fixed more connection problems.

Installed hrev56364 x86_64. No wifi connectivity until after making a wired connection and updating wpa_supplicant. The new wpa_supplicant needs to be included with the nightly image.
